Airbus Defense and Space

<p><strong>Customer Need:</strong> Airbus Defense and Space, in collaboration with the European Space Agency (ESA), sought to ensure the reliability and effectiveness of the Jupiter Icy Moons Explorer (JUICE) Spacecraft's Thruster Tranquillisation Mode. In particular, the focus was on ensuring stability during various phases, including Earth fly-bys, and guaranteeing robust control across multiple scenarios.</p><p></p><p><strong>Derived Solution:</strong></p><ol><li><p><strong>Controller Design and Tuning</strong>: A multidisciplinary approach was employed, centering on optimal controller design and tuning. This encompassed nonlinear control law adjustments tailored to the JUICE Spacecraft.</p></li><li><p><strong>Optimal Sensor Fusion and State Estimation</strong>: Innovations were introduced to achieve a synergy of sensors and enhanced state estimation capabilities for improved spacecraft control.</p></li><li><p><strong>System Performance Verification</strong>: Monte-Carlo methods, known for their reliability in complex systems, were utilized to verify the performance of the JUICE Spacecraft systems.</p></li></ol><p></p><p><strong>Value Delivery:</strong></p><ul><li><p><strong>Enhanced Spacecraft Stability</strong>: Successfully identified and addressed a crucial non-convergence issue, ensuring the spacecraft’s stability when transitioning out of the Thruster Tranquillisation Mode.</p></li><li><p><strong>Boosted Confidence in Earth Fly-Bys</strong>: Introduced innovative 'robustness' test scenarios, heightening confidence in the spacecraft's capability to diminish potentially harmful structural modes during abnormal Earth fly-by conditions.</p></li><li><p><strong>Advanced Verification Framework</strong>: Elevated the Monte-Carlo frameworks, which is crucial for the statistical verification of intricate spacecraft control systems.</p></li></ul>

Ensured the robustness and reliability of the ESA's Jupiter Icy Moons Explorer (JUICE) Spacecraft's Thruster Tranquillisation Mode. Through optimal controller design, nonlinear control law tuning, advanced sensor fusion, and state estimation, critical issues like potential non-convergence during mode transitions were identified and rectified. Leveraging Monte-Carlo methods, enhanced system performance verification frameworks were established, culminating in increased confidence in the spacecraft's capability, especially during Earth fly-bys.

Student Facilities

<p>The client needed a platform to help business schools student choose an abroad school, for the mandatory 1 year transition scholarship.</p><p>A lot of schools exist, but student had no objective data to compare them, except what the school wrote, which was most of the time about the location, price and program.</p><p></p><p>The student wanted to allow schools to say more about them, their campuses, what made them unique. I built several forms (around 50 questions) to help school manager bring the most of their schools, allowed students to leave review about the schools (reviews were moderated, and schools were able to respond, bringing the discussion to a new level), we also leveraged a job board, talked about everyday life, transport means, schools associations and extra scholar life...</p><p></p><p>The website is built on Laravel, HTML/CSS3/Jquery, multilingual, and hosted on Google Cloud Platform, with all security and backup automation needed.</p><p>That was a year long, 100k budget project, which i drove by myself</p><p></p><div class="image-container"><div class="image-row-wrapper"><div class="image-wrapper"><img src="https://cdn.collective.work/cleykak4d0u6f5wer2jdt7qh4.jpg"><div class="image-overlay"></div></div></div></div><div class="image-container"><div class="image-row-wrapper"><div class="image-wrapper"><img src="https://cdn.collective.work/cleykavxe0u6l5wer5oe5c8yi.png"><div class="image-overlay"></div></div></div></div><div class="image-container"><div class="image-row-wrapper"><div class="image-wrapper"><img src="https://cdn.collective.work/cleykb9ik0tfk5xhl4kim4lej.png"><div class="image-overlay"></div></div></div></div><div class="image-container"><div class="image-row-wrapper"><div class="image-wrapper"><img src="https://cdn.collective.work/cleykbfr20tfo5xhlfz7z4cz6.png"><div class="image-overlay"></div></div></div></div>
